1. General

1.1. Motor Design

The POWERPACTM

and POWERMAX IIStep motors provide an excellent torque to frame size ratio.Optimized magnetic design in combination with a new rotor/stator design produce more torque and a higher

acceleration. This unique design also reduces the detent torque for smoother microstepping.The motors are available in several frame sizes and offer holding torques of 0,42 Nm up to 40,2 Nm. Themotors of the M and K series incorporate the patented flux focusing technology (Sigmax

) and provide a per-

formance increase of 20% to 30% at identical motor size.

1.1.1. SigmaxTechnology

Due to their unique stator construction the Sigmax

motors produce a higher torque rate than comparably si-zed standard motors.Thin rare-earth-magnets are embedded into the stator gashes. The polarization concentrates the flux whichis produced in the rotor magnets onto the stator teeth. Thus the flux leakage that occurs on certain rotor-to-stator positions is inhibited.

Standard Hybrid Step Motor SigmaxHybrid Step Motor(Series P and N) (Series M and K)

Typical path of flux transfer in an energizedconventional hybrid step motor. Some fluxleakage occurs in normal operation.

Patented Sigmaxtechnology redirectsmagnetic flux to inhibit leakage and optimizetorque production.
